A recent UNICEF report has stated how toxic air damages a child’s brain, leading to anxiety, and development delays. Here’s what you can do to keep yourself and your child safe.

Last month, New Delhi caught in the throes of severe toxic smog, was given the unenviable rank of the world’s worst polluted city by the World Health Organization (WHO). Some leading news websites even carried findings, which stated how breathing in the Indian capital in the month of November was like smoking 50 cigarettes a day.
Gopal Bharati, a resident of Safdarjung Enclave vouches for this. A resident of Delhi for the past ten years, he has been a witness to the deteriorating air quality over the years. “The situation is really bad. My office has been closed since Tuesday and we are forced to use masks whenever we go out. But, even that is not of much help.”
Now, at a time when India, particularly the north region, is staring at a pollution crisis, a UNICEF report has again put the focus on the hazards of air pollution. The report says there is a growing body of scientific research that shows air pollution can do permanent damage to a child’s brain. The report titled “Danger in the air” explains how exposure to certain air pollutant particles can lead to oxidative stress, resulting in neurodegenerative diseases.
“Not only do pollutants harm babies’ developing lungs, they can permanently damage their developing brains and, thus, their future,” Unicef executive director Anthony Lake said.
According to a study conducted in Mexico, children were taken from both polluted areas and non-polluted areas. The study showed the presence of white matter hyperintense lesions in children living in polluted areas as against children not living in polluted areas. Increased white matter hyperintensities are associated with a higher risk of stroke and dementia, as well as high mortality.
“Pollution affects the development of children due to the presence of toxins. Children’s brains are still developing making them vulnerable to the negative effects of air pollution,” says Dr Jamuna.
The pre-frontal cortex, responsible for many of cognitive functions like attention, planning, and decision-making is the last to develop in children and adolescents. The posterior part of the brain develops earlier as compared to the anterior part of the brain.
Dr. Jamuna also suggests parents should try to keep their children away from air pollution. She further suggests that a child who has developed health problems from living in a polluted area, when shifted to a non-polluted area might show health improvement.
For reporting the daily air quality, agencies rely on the Air Quality Index (AQI), which tells how clean or polluted the air is and the associated health effects. It primarily focuses on health hazards of inhaling polluted air over a period, ranging from a few hours to a couple of days. The higher the AQI value, the greater the level of air pollution and health concern.
For instance, an AQI value of 50 represents good air quality while an AQI value over 300 represents hazardous air quality.
According to a report by Greenpeace India titled 'Airpocalypse' published in 2017, as many as 1.2 million deaths take place every year due to air pollution in India. Children who suffer from asthma or lung problems are at a greater risk. In October 2016, UNICEF released a report stating that air pollution kills 600,000 children every year throughout the world.
Air pollution is a serious issue that needs to be addressed by both the government and the public. Here are a few tips for parents to fight this menace and keep their children safe:
1) No outdoor activities during the early morning:
We have all been brought up believing that early morning is the best time to indulge in outdoor activities because the air is 'supposed' to be pure during this time. However, this is not the case. Air quality might be equally bad like any other time of the day. You should check the air quality index before you let your children go out during the early morning.
2) Use air purifiers:
Using air purifiers is one way to combat air pollution. More households today are using air purifiers to clean pollutants inside the house. Good quality air purifiers are effective in purifying the air, removing dust, smoke, allergens and pollens.
3) Use pollution masks:
With the alarming rise in pollution levels, the sale of pollution masks in Delhi has increased considerably. Pollution masks help to filter pollution and ensure your child can breathe in clean and pure air. Medical experts have advised N95 and N99 pollution mask to be most effective. If you are unable to purchase one, use a cloth to cover up your face.
4) Avoid using cars and bikes:
Fuel emission is a major reason for air pollution. So, if you have to go to a place that is not far, take a walk or ride a bicycle. For long distances, you could always use a public mode of transport like the bus or the metro.
5) Avoid smoking:
There could not be a better time to quit smoking. The residual gas and particles emitted from cigarette smoking pose many health hazards. It can lead to chronic heart and lung problems for the active and passive smokers.
6) Eat a healthy diet:
A diet rich in nutrients can also play a major role in combating air pollution. Add jaggery and honey to your diet to boost your immune system that help to flush off air pollutants that might enter through the mouth and nose.
7) Keep indoor plants:
Improve the quality of air indoors by keeping a variety of indoor plants. Try to keep plants like aloe vera, spider plant, snake plant, bamboo palm, etc.
Each country has devised a particular method of controlling air pollution. This video looks at how developed and developing countries differ in their way of tackling air pollution.
In case you think air pollution is extremely high in the area you live in, you can restrict the time your child spends outdoors. If your child complains of sore eyes, cough, or a sore throat, immediately prevent her from playing outdoors and connect with a doctor, if required.
